Description

  The present invention relates to a rotary gas treatment device used as a dry air supply device, an inert gas dehumidifier, an organic solvent adsorption device, and the like, and a rotor element structure used for the rotary gas treatment device.

  The basic structure of a rotary gas processing device used as a dry air supply device, an inert gas dehumidifier, an organic solvent adsorption device, etc. is such that the honeycomb-shaped rotor element structure and the rotor element structure rotate freely. The casing is provided with a fixed plate that forms a processing zone and a regeneration zone on both sides in the axial direction of the rotor element. Various types of rotor element structures are known for use in these rotary gas processing apparatuses.

  Japanese Patent Application Laid-Open No. 2004-113844 relates to a honeycomb-like adsorption rotor, in which a central boss and an outer peripheral plate are fixed with plate-like spokes, and the fixing is fixed with bolts, and a large force is applied to the honeycomb body. I do not take it. In addition, the honeycomb body is disclosed in the shape of eight fans mounted between the spokes.

  Japanese Patent Laid-Open No. 2001-276552 discloses a cylindrical shape in which a rotor is formed by an arc-shaped sector composed of a gas adsorbing element having a honeycomb structure having a large number of small through holes partitioned in a circular arc shape by radially extending spokes. 2 are respectively arranged in the rim of each of these, and are integrated with a caulking material such as silicone between the joint surfaces of the respective sectors and the spokes and the rim, and contact the axial end surface of the spoke with the end surface and both sides of the end surface. There is disclosed a rotor for a rotary adsorber provided with a heat-shielding seal made of a non-combustible material plate covering a joint portion of the two arcuate sectors.

As described above, the conventional rotor element structure (adsorption rotor) has a plate-like spoke having a central boss and a cylindrical outer peripheral plate (rim) so that a large force does not act on the honeycomb-like rotor element. The honeycomb body having a fan-shaped cross section is mounted on eight fan-shaped small through holes formed between the outer peripheral plate and the spokes.
JP 2004-113844 A (Claim 1, paragraph numbers 0014 to 0016) JP 2001-276552 A (Claim 1, FIG. 1, FIG. 10) Japanese Unexamined Patent Publication No. 2003-126641 (Claims, FIGS. 3 to 5)

  However, since the conventional rotor element structure has eight plate-like spokes attached to the apparent cylindrical honeycomb-shaped rotor element in the axial direction, the rotor element area that can be effectively used is reduced, There is a problem that processing efficiency is poor. Further, since the plate-like ribs are provided over the entire axial length of the apparent cylindrical honeycomb-shaped rotor element, there is a problem that the rotor element structure becomes heavy and power consumption required for rotation is high.

  Accordingly, an object of the present invention is to provide a rotor element structure in which a large force does not act on a honeycomb-shaped rotor element, a large effective processing area in the rotor element can be taken, and the weight is suppressed.

  That is, the present invention solves the above-described conventional problem, and covers a honeycomb-shaped rotor element having a non-penetrating groove on both end faces and a central hole penetrating in the center, and an outer periphery of the rotor element. An outer peripheral ring, a cylindrical boss portion that fits into the center hole, and a plate-like rib that connects the outer ring and the boss portion and fits into one non-through hole of the honeycomb-like rotor element. A first frame, an outer ring that covers the outer periphery of the rotor element, a cylindrical boss that fits into the center hole, the outer ring and the boss, and the other of the honeycomb rotor elements A second frame formed of a plate-like rib that fits into the non-through hole, an outer peripheral panel that connects the first frame and the second frame, a tip portion inside the boss portion of the first frame, A tip part inside the boss part of the second frame; There is provided a rotor element structure, characterized in that the rotor element structure, characterized in that fitted.

  The present invention also provides a rotary gas processing apparatus comprising the rotor element structure.

  In the rotor element structure of the present invention, the outer cylinder frame of the honeycomb-like rotor element is composed of three members, the first frame, the second frame, and the outer peripheral panel, and the plate-like ribs (only on the first frame and the second frame) The same as plate-like ribs) is provided, so that the effective processing area in the rotor element can be increased and the weight can be reduced while maintaining a structure in which a large force does not act on the honeycomb-like rotor element as in the past. it can.

  Next, a rotor element structure according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of the rotor element structure of this example, and FIG. 2 is an exploded perspective view of the rotor element structure of this example.

  The rotor element structure 10 of the present example includes a honeycomb-shaped rotor element 1 having a columnar appearance and an outer cylinder frame 2 that covers a circumferential portion of the rotor element 1.

  The honeycomb-like rotor element 1 is provided with a non-penetrating groove on both end faces toward the axial center and a central hole penetrating in the axial direction at the center in the radial direction. That is, the honeycomb-like rotor element 1 has a non-through groove that is divided into three sectors in the circumferential direction at a predetermined depth from one end surface 11a (right side in FIG. 2) of the cylindrical object toward the center in the axial direction. 12 a and a non-penetrating groove 12 b that is divided into three fan-like shapes in the circumferential direction at a predetermined depth from the other end surface 11 b (left side in FIG. 2) of the cylindrical object toward the center in the axial direction. The center hole 13 is provided in the center of the direction through which the boss portions 42a and 42b of the first frame and the second frame are inserted. The plate-like rib 3 of the first frame 2a is fitted into the non-penetrating groove 12a, and the plate-like rib 3 of the second frame 2b is fitted into the non-penetrating groove 12b.

  The non-penetrating grooves 12a and 12b are not limited to three and may be four or more. Further, the number of installations in the non-penetrating grooves 12a and 12b may be the same or different from each other, but the same is preferable in that the production efficiency is improved. If there are two non-penetrating grooves 12a and 12b, the cylindrical shapes of the first frame 2a and the second frame 2b cannot be maintained and are easily decentered, and if they are too many, the effective processing area in the honeycomb is reduced. become. In the present specification, when both the first frame and the second frame are described, “first” and “second” may be omitted.

  The depth (axial length) of the non-penetrating groove 12a or non-penetrating groove 12b varies depending on the strength of the rotor element 1, the processing area of the rotor element 1, the mounting stability of the frame, etc. Each of them is about 1/10 to 1/3 of the entire length of the rotor element 1. If the depth of the non-penetrating groove 12a or the non-penetrating groove 12b is too shallow, the mounting stability of the frame is lowered, and if too deep, the processing area of the rotor element 1 is lowered and the strength is lowered. In this example, the depth of the non-penetrating grooves 12a and 12b is set so that when the frames 2a and 2b are attached to the rotor element 1, the front end portion (first fitting portion) in the axial direction of the boss portion 4a of the first frame 2a. ) 42a and the tip end (second fitting) 42b on the inner side in the axial direction of the boss 4b of the second frame 2b are fitted to each other, and the tips 31a and 31b on the outer side of the plate-like rib 3 and the end face of the rotor element 1 11a and 11b are dimensions that are flush with each other. The three-divided area formed by the non-penetrating grooves 12a and 12b has nothing to do with the zone-divided areas of the processing zone and the reproduction zone.

  The center hole 13 is a hole formed in the radial center of the cylindrical rotor element 1 and penetrating in the axial direction, and is substantially the same as the outer diameter of the boss portions 4a and 4b of the first frame 2a and the second frame 2b. Has an inner diameter.

  The first frame 2a is fitted to one end face side (the right side in FIGS. 1 and 2) of the rotor element 1, and is positioned at the radial center and is fitted to the inner end in the axial direction. A boss portion 4a having a predetermined length having a portion 42a and three plate-like ribs 31a that extend radially from the boss portion 4a and fit into the non-penetrating groove 12a connected to the cylindrical outer ring 32a. The number of plate-like ribs 31a is the same as the number of non-through grooves 12a formed in the rotor element 1. If there are three plate-like ribs 31a, the outer peripheral ring 32a will not be decentered, and the processing area of the rotor element 1 will not be reduced.

  Further, the width dimension (length in the axial direction) of the plate-like rib 31a is the same as the depth of the non-penetrating groove 12a, and is the same as the width dimension of the outer peripheral ring 32a. That is, the outer end surface 33a in the axial direction of the outer peripheral ring 32a and the outer end surface 31a of the plate-like rib 31a are the same surface. As a result, in the case of a rotary gas processing apparatus, the structure of a fixed plate having a zone forming function for forming a processing zone and a regeneration zone and a sealing function for an inter-zone seal and an outer seal for sealing the zone and the outside air is simplified. It can be. In this example, the first fitting portion 42a of the first frame 2a is a cylindrical female portion having a fitting hole 42a having an inner diameter substantially the same as the outer diameter of the cylindrical male portion of the second fitting portion 42b of the second frame 2b. It is.

  Four engaging members (engaging portions) 5 are attached to the outer peripheral portion of the first frame 2a at a predetermined pitch in the circumferential direction. When this engaging member 5 is a rotary gas processing device, it improves the engagement with an endless belt wound around this portion. Therefore, the same rubber material as the endless belt can be used.

  The second frame 2b is fitted to the other end face side (the left side in FIGS. 1 and 2) of the rotor element 1, and is positioned at the radial center and second fitted to the inner end in the axial direction. A boss portion 4b having a predetermined length having a portion 42b and three plate-like ribs 31b that extend radially from the boss portion 4b and fit into the non-penetrating groove 12b connected to the cylindrical outer ring 32b. The number of plate-like ribs 31b is the same as the number of non-through grooves 12b of the rotor element 1 formed. Further, the width dimension (length in the axial direction) of the plate-like rib 31b is the same as the depth of the non-penetrating groove 12b, and is the same as the width dimension of the outer peripheral ring 32b. That is, the outer end surface 33b in the axial direction of the outer peripheral ring 32b and the outer end surface 31b of the plate-like rib 31b are the same surface. The second fitting part 42b of the second frame 2b is a cylindrical male part having a boss hole 41b and an outer diameter smaller than the outer diameter of the boss part main body 411 in this example.

  Bearings (not shown) are inserted into the boss portions 4a and 4b of the first frame 2a and the first frame 2b. Thereby, rotation of the rotor element structure 10 becomes smooth.

  The outer peripheral panel 2c connects the first frame 2a and the second frame 2b, and is attached to the outer periphery of the central portion of the cylindrical rotor element 1 in the axial direction. In addition, the outer peripheral panel 2c of the present example is formed in a cylindrical shape by abutting the flange portions 24 that project the side ends of the half cylindrical members 25a and 25b outward.

  In order to form the rotor element structure 10, the plate-like ribs 31a of the first frame 2a and the plate-like ribs 31b of the second frame 2b are fitted into the non-penetrating grooves 12a and 12b of the rotor element 1, respectively. The second fitting portion 42b of the boss portion 4b of the second frame 2b is inserted into the first fitting object 42a of the boss portion 4a, and the rotor element 1 and the frames 2a and 2b are integrated. An adhesive may be used when the rotor element 1 and the frames 2a and 2b are fitted. Next, the semi-cylindrical members 25a and 25b are put on the outer periphery of the central portion of the rotor element 1, and the flange portions 24 are brought into contact with each other to be screwed. The screw holes 21 formed at a predetermined pitch in the circumferential direction of the edge in the width direction (axial direction) of the semi-cylindrical members 25a and 25b and the screw holes of the first frame 2a are replaced with the screw holes 21 and the second frame. Screw the 2b screw holes together. At this time, the outer peripheral surface of the rotor element 1 and the inner peripheral surfaces of the half-cylindrical members 25a and 25b may be joined with an adhesive. The rotor element structure 10 assembled in this way can maintain a structure in which a large force does not act on the honeycomb-like rotor element 1 as in the prior art, and can take a large effective processing area in the rotor element 1. Can be lightweight. The rotor element structure according to the present invention is particularly effective when the axial length of the rotor element 1 is long.

  The rotor element structure 10 is not limited to the above form. For example, the first fitting portion of the first frame 2a may be a cylindrical male portion, and the second fitting portion of the second frame 2b may be a cylindrical female portion. it can. Further, the engaging member 5 may be installed on the outer ring 32b of the second frame 2b, or may be installed on both the outer ring 32a of the first frame 2a and the outer ring 32b of the second frame 2b. Further, the joining between the outer peripheral panel 2c and the first frame 2a and the joining between the outer peripheral panel 2c and the second frame 2b may be joining by welding or joining by an adhesive. Further, the outer peripheral panel 2c may be a cylindrical member from the beginning. When the outer peripheral panel 2c is a cylindrical member, the outer peripheral panel 2c is first assembled to the rotor element 1, and then the first frame 2a and the second frame 2b are assembled. Further, the engaging member 5 may be formed over the entire peripheral surface of the outer peripheral ring 32a of the first frame 2a.

  The rotary gas processing apparatus of the present invention includes a rotor element structure 10. The rotary gas processing apparatus defines, in addition to the rotor element structure 10, end faces 11a and 11b of the rotor element 1 into at least a processing zone and a regeneration zone, a fixed plate having a sealing means, a gas supply means to be processed, Known devices such as a gas to be processed supply pipe, a process gas outflow pipe, a regeneration gas supply pipe, a regeneration gas outflow pipe, a casing, and a rotor element structure rotating means are installed. In addition, when the rotary gas processing apparatus of this example is an inert gas dehumidifier, each zone is a dehumidification zone, a regeneration zone, and a cooling zone, for example. When the rotary gas processing apparatus is an organic solvent adsorption apparatus, each zone is, for example, an adsorption zone and a regeneration zone, or an adsorption zone, a regeneration zone, and a cooling zone.

  In the rotary gas processing apparatus of the present invention, an example of a fixed plate that defines the end faces 11a and 11b of the rotor element 1 at least in a processing zone and a regeneration zone and includes a sealing means will be described with reference to FIG. In FIG. 3, since the fixing plates 6a and 6b are symmetrical members having the same shape, only one fixing plate 6a will be described. The fixed plate 6a is usually fixed to the casing of the rotary gas processing device, and defines the end face of the rotor element 1 into a processing zone 65, a regeneration zone 63, and a cooling zone 64, and the axial direction of the outer peripheral ring 32a. An annular seal portion 61 having a flat surface that is in sliding contact with the outer end 33a of the rotor, and an annular seal portion 61 that is in sliding contact with the end surface 11a of the rotor element 1 and that defines the end surface of the rotor element 1 for each zone. The zone seal portion 62 is provided. A shaft hole 66 through which the connecting rod passes is formed at the center. The annular seal portion 61 and the zone seal portion 62 may be simply referred to as “seal portion”.

  The ring shape of the annular seal portion 61 may be the same as the ring shape of the outer end 33a of the outer peripheral ring 32a of the frame 2a and a width larger than the end face width of the outer end 33a. Thereby, the outer side end 33a can be covered with the annular seal part 61, and it can seal completely.

  The zone seal portion 62 has a partition function and a seal function that define the end face of the rotor element 1 for each zone. That is, the seal portion formed of the annular seal portion 61 and the zone seal portion 62 has a shape of a large ring shape portion having a predetermined width and a small return shape portion having a predetermined width coaxial with the large return shape as viewed from the side, that is, in the rotation axis direction. And it becomes a long-shaped part which divides between zones while connecting a large ring shape part and a small return shape part.

Width _{w 1} of zone seal portions 62, can not be unconditionally determined by the size of the rotor element 1, is generally 10 to 30 mm. If w ₁ is in this range, even if there are large and small irregularities in the rotor element, the inter-zone sealing can be performed reliably. zone between the seal when w ₁ is too small is insufficient, the effective processing area narrowed too large zone is reduced.

Further, the width _{w 2} of the annular seal portion 61 is approximately 10 to 30 mm. When w ₂ is too large effective processing area of the rotor element are reduced.

  For example, the fixed plate 6a has a seal portion formed on one surface of a metal plate 601 such as SUS in which a shaft hole 66 through which a connecting rod (not shown) passes in the center. As the seal part, foam metal such as Fluoroflex (registered trademark), silicone foam, etc. are attached to the metal plate 601 side (inner layer part), and a heat-resistant sheet is attached to the sliding contact part side above it. (Sliding contact portion). Fluoroflex is a closed-cell sheet foam made by foaming fluoro rubber, which has excellent heat resistance and compression recovery characteristics, has low degassing components during heating, and is dried in a room where equipment that requires a clean environment is operating. This is suitable for supplying air.

  The heat-resistant sheet has heat resistance that can withstand temperatures of 200 ° C. or higher, and examples thereof include a PTFE resin sheet. If a heat-resistant sheet is used for the sliding contact portion of the annular seal portion 61 and the zone seal portion 62, smooth sliding can be realized at the seal portion even when high-temperature desorption air of 300 ° C or higher flows in the regeneration zone. Particles that are sometimes generated can be reduced.

  To assemble the rotor element structure 10 and the fixing plates 6a and 6b, first, fix the plates 6a and 6b to the boss holes of the rotor element structure 1 and the shaft holes of the fixing plates 6a and 6b at both ends of the rotor element structure 10. Are fitted to each other, and a connecting rod is passed through the central shaft hole 66 and both ends are tightened with bolts. The rotor element structure 10 and the fixing plates 6a and 6b are tightened so that the compressive load is 0.01 to 0.2 MPa. Thereby, smooth rotation and reliable sealing of the rotor element structure 10 can be expressed.

  In the rotor element structure 10 to which the fixed plates 6a and 6b are mounted, the fixed plates 6a and 6b and the casing are fixed, the gas supply means to be processed is provided on the inlet side of the processing zone 65, and the outlet side of the processing zone 65 is provided. A processing gas outflow pipe is provided at the inlet side of the regeneration zone 63, a regeneration gas supply pipe is provided at the outlet side of the regeneration zone 63, a regeneration gas outflow pipe is provided at the inlet side of the cooling zone 64, and a cooling gas supply pipe is provided at the cooling zone 64. A cooling gas outflow pipe is connected to an outlet side of 64, and an endless belt having one end hooked on a rotating means is connected to the engaging member 5 of the outer peripheral ring 32a of the first plate 2a, thereby constituting a rotary gas processing apparatus. .

  Examples of the rotary gas treatment device of the present invention include a dry air supply device, an inert gas dehumidifier, and an organic solvent adsorption device.

  According to the rotor element structure of the present invention, the outer cylinder frame of the honeycomb-like rotor element is constituted by three members of the first frame, the second frame, and the outer peripheral panel, and the plate shape is formed only on the first frame and the second frame. Since the ribs are provided, the effective processing area in the rotor element can be increased and the weight can be reduced while maintaining a structure in which a large force does not act on the honeycomb-like rotor element as in the prior art. Further, according to the rotary gas processing apparatus of the present invention, the power consumption required for the rotation of the rotor element structure can be suppressed and the inter-zone seal and the outer seal can be stably performed, so that the gas processing efficiency is improved.
